REPORT OF INDEPENDENT AUDITORS

TO THE SHAREHOLDERS OF
AETERNA LABORATORIES INC.


We have audited the consolidated balance sheets of AETERNA LABORATORIES INC.
as at December 31, 2003 and 2002 and the consolidated statements of
operations, deficit, other capital and cash flows for each of the years in
the three-year period ended December 31, 2003. These financial statements are
the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with Canadian generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.

In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the Company as at December
31, 2003 and 2002 and the results of its operations and its cash flows for
each of the years in the three-year period ended December 31, 2003 in
accordance with Canadian generally accepted accounting principles.

1     INCORPORATION AND NATURE OF ACTIVITIES

      AEterna Laboratories Inc. ("AEterna or the "Company"), incorporated under
      the Canada Business Corporations Act, is organized into three operating
      segments. The biopharmaceutical segment focuses on the development of
      novel therapeutic approaches with an extensive product portfolio,
      including two already marketed and several other products in early and
      late-stage development in oncology, endocrinology and infectious diseases.
      Cetrorelix is sold in the United States and Europe to the IN VITRO
      fertilization market, and is in Phase II clinical trials for
      endometriosis, uterus myoma and enlarged prostate. Miltefosine is sold for
      black fever and has successfully completed a Phase III trial in parasitic
      skin disease.

      The cosmetics and nutrition segment is dedicated to the development,
      manufacturing and marketing of cosmetics, active ingredients and
      nutritional products. The distribution segment specializes in value-added
      services by supporting innovation, importing and distributing raw
      materials and high-end brand-name activities. These two segments are
      operated by Atrium Biotechnologies Inc. and its subsidiaries.

      On December 17, 2003, the Company decided to stop the clinical development
      in renal cell carcinoma with Neovastat (R). The Company continues to
      develop fourteen products and to market two others in different
      indications including Neovastat (R) which is in phase III in non-small
      cell lung cancer.

      ACCOUNTING ESTIMATES

      The preparation of financial statements in conformity with Canadian
      generally accepted accounting principles requires management to make
      estimates and assumptions that affect the amounts of assets and
      liabilities reported in the financial statements. Those estimates and
      assumptions also affect the disclosure of contingencies at the date of the
      financial statements and the reported amounts of revenues and expenses
      during the years. Significant estimates include the allowance for doubtful
      accounts, provisions for obsolete inventory, future income tax assets, the
      useful lives of property, plant and equipment, the valuation of intangible
      assets and goodwill, the fair value of options granted and certain accrued
      liabilities. Actual results could differ from those estimates.

      FOREIGN CURRENCY TRANSLATION

      Foreign subsidiaries

      Zentaris GmbH ("Zentaris"), a German subsidiary of AEterna and Atrium
      Biotech USA inc., a subsidiary of Atrium, are considered to be integrated
      foreign operations. As a result, the foreign subsidiaries' accounts are
      translated into Canadian dollars using the temporal method. Under this
      method, monetary assets and liabilities are translated at the exchange
      rates in effect at the balance sheet date. Non-monetary assets and
      liabilities are translated at historical rates. Revenues and expenses are
      translated at the average rate for the year. Gains and losses resulting
      from translation are reflected in the statement of operations.

      Unipex Finance S.A. ("Unipex") and its subsidiaries, Interchemical S.A.
      and Chimiray S.A., as well as Siricie S.A., which are all French
      subsidiaries of Atrium, are considered to be self-sustaining foreign
      operations. As a result, the foreign subsidiaries' financial statements,
      whose functional currency is other than the Canadian dollar, are
      translated into Canadian dollars using the current rate method. Under this
      method, assets and liabilities are translated at the exchange rates in
      effect at the balance sheet date and revenues and expenses are translated
      at the average rate for the year. Gains and losses resulting from
      translation are deferred in the "Cumulative translation adjustment"
      account under "Shareholders' Equity".

      Transactions denominated in foreign currencies are translated into
      Canadian dollars as follows:

           Monetary assets and liabilities are translated at the exchange rate
           in effect at the balance sheet date and revenues and expenses are
           translated at the monthly average exchange rate. Non-monetary assets
           and liabilities are translated at historical rates. Gains and losses
           arising from such translation are reflected in the statements of
           operations.

      CASH AND CASH EQUIVALENTS

      Cash and cash equivalents consist of cash on hand and balances with banks,
      exclusive of bank advances, as well as all highly liquid short-term
      investments. The Company considers all highly liquid short-term
      investments having a term of less than three months at the acquisition
      date to be cash equivalents.

      SHORT-TERM INVESTMENTS

      Short-term investments, which are valued at the lower of amortized cost
      and market value, are mainly composed of bonds which do not meet the
      Company's definition of cash and cash equivalents.

      INVENTORY

      Inventory is valued at the lower of cost and market value. Cost is
      determined using the first in, first out basis. Cost of finished goods
      includes raw materials, labour and manufacturing overhead under the
      absorption costing method. Market value is defined as replacement cost for
      raw materials and as net realizable value for finished goods.

      PROPERTY, PLANT AND EQUIPMENT AND DEPRECIATION

      Property, plant and equipment are recorded at cost, net of related
      government grants and accumulated depreciation. Depreciation is calculated
      using the following methods and annual rates:

</Table>

      The carrying value of property, plant and equipment is evaluated whenever
      significant events occur which may indicate a permanent impairment in
      value, based upon a comparison of the carrying value to the fair value.

      DEFERRED CHARGES

      Deferred charges relate to deferred upfront payments made by a subsidiary
      in connection with research and development collaborations and to
      financing charges. These deferred charges are included in the statement of
      operations over the progress of the research and development work related
      to the contracts and on the term of the convertible term loans,
      respectively.

      INTANGIBLE ASSETS

      Intangible assets consist of patents, trademarks, licenses, distribution
      agreements and organization costs. Patents and trademarks represent costs,
      including professional fees, incurred for the filing of patents and the
      registration of trademarks for product marketing and manufacturing
      purposes, net of related government grants and accumulated amortization.
      Intangible assets are amortized on a straight-line basis over their
      estimated useful lives of eight to fifteen years for patents, ten years
      for trademarks, licenses and distribution agreements, and three to five
      years for organization costs, which are fully amortized as at December 31,
      2003.

-------------------------------------------------------------------------------

(tabular amounts in thousands of Canadian dollars,
except share/option and per share/option data and as otherwise noted)



      Intangible assets with finite lives are reviewed for impairment when
      events or circumstances indicate that costs may not be recoverable.
      Impairment exists when the carrying value of the assets is greater than
      the undiscounted future cash flows expected to be provided by the asset.
      The amount of impairment loss, if any, is the excess of its carrying value
      over its fair value. Finite-lived intangible assets are written down for
      any permanent impairment in value of the unamortized portion. As at
      December 31, 2003, there were no events or circumstances indicating that
      the carrying value may not be recoverable. The Company does not have
      indefinite-lived intangible assets.

      GOODWILL

      Goodwill represents the excess of the purchase price over the fair values
      of the net assets of entities acquired at the respective dates of
      acquisition. Goodwill is tested annually, or more frequently if impairment
      indicators arise, for impairment in relation to the fair value of each
      reporting unit to which goodwill applies and the value of other assets in
      that reporting unit. An impairment charge is recorded for any goodwill
      that is considered impaired.

      EMPLOYEE FUTURE BENEFITS

      Some of the Company's subsidiaries maintain defined benefit plans and two
      defined contribution plans for their employees. These subsidiaries accrue
      their obligations under employee benefit plans and the related costs. In
      this regard, the following policies have been adopted:

      o    The cost of pension and other retirement benefits earned by employees
           is actuarially determined using the projected unit credit method and
           benefit method prorated on service and management's best estimate of
           salary escalation and retirement ages of employees.

      o   The net actuarial gain (loss) of the benefit obligation is reported
          in the statement of operations as it arises.

      DEFERRED REVENUES

      Deferred revenues relate to upfront payments received by a subsidiary in
      connection with research cooperation agreements. These revenues are
      included in the statement of operations based on the progress of the
      research and development work related to the contracts.

      REVENUE RECOGNITION

      The biopharmaceutical segment is currently in a phase in which potential
      products are being further developed or marketed jointly with strategic
      partners. The existing cooperation and royalty agreements usually foresee
      one-time payments (upfront payments), payments for research and
      development services in the form of cost reimbursements, milestone
      payments and royalty receipts for licensing and marketing product
      candidates.

      Payments received at the beginning of research cooperation agreements
      (upfront payments) are not recorded as revenue when received but are
      amortized based on the progress of the research and development work
      concerned.

-------------------------------------------------------------------------------

(tabular amounts in thousands of Canadian dollars,
except share/option and per share/option data and as otherwise noted)

      Milestone payments are recognized when appropriate development results are
      achieved and agreed by the customer. Royalty receipts for marketing
      products are only to be paid by cooperation and royalty partners when
      product revenues are achieved and are accordingly first recorded as
      revenues by the Company at such time.

      Revenues from sales of products are recognized, net of estimated sales
      allowances and rebates, when title passes to customers, which is at the
      time goods are shipped.

      INCOME TAXES

      The Company follows the liability method of accounting for income taxes.
      Under this method, future income tax assets and liabilities are determined
      according to differences between the carrying amounts and tax bases of the
      assets and liabilities. Changes in the net future income tax assets or
      liabilities are included in the statement of operations. Future income tax
      assets and liabilities are measured using substantively enacted tax rates
      and laws expected to apply in the years in which assets and liabilities
      are expected to be recovered or settled.

      The Company establishes a valuation allowance against future income tax
      assets if, based on available information, it is not more likely than not
      that some or all of the future income tax assets will be realized.

      RESEARCH AND DEVELOPMENT TAX CREDITS AND GRANTS

      The Company is entitled to scientific research and experimental
      development ("SR&ED") tax credits granted by the Canadian federal
      government ("Federal") and the government of the Province of Quebec
      ("Provincial"). Federal SR&ED tax credits are earned on qualified Canadian
      SR&ED expenditures at a rate of 20% and can only be used to offset Federal
      income taxes otherwise payable. Refundable provincial SR&ED tax credits
      are generally earned on qualified SR&ED salaries, subcontracting and
      university contract expenses incurred in the Province of Quebec, at a rate
      of 17.5% (20% in 2002).

      SR&ED tax credits and grants are accounted for using the cost reduction
      method. Accordingly, tax credits and grants are recorded as a reduction of
      the related expenses or capital expenditures in the period the expenses
      are incurred. The refundable portion of SR&ED tax credits is recorded in
      the year in which the related expenses or capital expenditures are
      incurred and the non-refundable portion of SR&ED tax credits and grants is
      recorded at such time, provided the Company has reasonable assurance the
      credits or grants will be realized.

      RESEARCH AND DEVELOPMENT COSTS

      Research costs are expensed as incurred. Development costs are expensed as
      incurred except for those which meet generally accepted criteria for
      deferral, which are capitalized and amortized against operations over the
      estimated period of benefit. As at December 31, 2003, no costs have been
      deferred.

      LOSS PER SHARE

      In order to calculate the loss per share, subordinate and multiple voting
      shares are considered as common shares.

      The basic net loss per share is calculated using the weighted average
      number of common shares outstanding during the year.

      The diluted net loss per share is calculated based on the weighted average
      number of common shares outstanding during the year, plus the effects of
      dilutive common share equivalents such as options, warrants and
      convertible term loans. This method requires that the diluted net loss per
      share be calculated using the treasury stock method, as if all common
      share equivalents had been exercised at the beginning of the reporting
      period, or period of issuance, as the case may be, and that the funds
      obtained thereby were used to purchase common shares of the Company at the
      average trading price of the common shares during the period.


3     CHANGES IN ACCOUNTING POLICIES

      a)    YEAR ENDED DECEMBER 31, 2003

      STOCK-BASED COMPENSATION PLANS

      On January 1, 2002, the Company adopted the recommendations of Canadian
      Institute of Chartered Accountants ("CICA") Handbook Section 3870
      STOCK-BASED COMPENSATION AND OTHER STOCK-BASED PAYMENTS. This Section
      establishes standards for the recognition, measurement and disclosure of
      stock-based compensation made in exchange for goods and services and
      requires the use of the fair value method to account for awards to
      non-employees and direct awards of stock to employees and encourages, but
      does not require, the use of the fair value method to account for
      stock-based compensation costs arising from awards to employees. On
      October 15, 2003, this section was amended to require expensing of all
      stock-based compensation awards in the financial statements for fiscal
      years beginning on or after January 1, 2004 with early adoption
      encouraged. In accordance with the transitional provisions of this
      section, the Company has decided to adopt the revisions in the current
      year and used the prospective method as a transitional method, as
      permitted under those amendments. According to this method, all
      stock-based compensation granted during the twelve-month period ended
      December 31, 2003 have been recorded in the corresponding period without
      restatement of prior years. However, the Company is still required to
      provide pro-forma disclosures relating to net loss and net loss per share
      as if stock-based compensation costs had been recognized in the financial
      statements using the fair value method for options granted in 2002. These
      disclosures have been presented in note 15.

      IMPAIRMENT OF LONG-LIVED ASSETS

      In December 2002, the CICA issued Handbook Section 3063, "Impairment of
      Long-lived Assets", which is effective for fiscal years beginning on or
      after April 1, 2003 with early adoption encouraged. Under this Section, an
      impairment loss is measured as the difference between the carrying value
      of an asset and its fair value. The Company adopted this Section in 2003
      without effect on operations or balance sheets.

except share/option and per share/option data and as otherwise noted)


      DISCLOSURE OF GUARANTEES

      On January 1, 2003, the Company prospectively adopted Accounting Guideline
      14 of the CICA Handbook, "Disclosure of Guarantees". This new guideline
      requires certain disclosure about obligations under guarantees other than
      product warranties. The adoption of this guideline had no impact on the
      Company's financial statements since the Company has no guarantee that
      falls into the scope of this new guideline.

      DISPOSAL OF LONG-LIVED ASSETS AND DISCONTINUED OPERATIONS

      On May 1, 2003, the Company prospectively adopted Section 3475 of the CICA
      Handbook, "Disposal of Long-Lived Assets and Discontinued Operations".
      Under this new section, a long-lived asset to be disposed of other than by
      sale continues to be classified as held and used until it is disposed of;
      a long-lived asset classified as held for sale is measured at the lower of
      its carrying value of fair value less cost to sell; a loss recognized on
      classification of long-lived assets as held for sale or a group of assets
      as a discontinued operation does not include future operating losses,
      other than to the extent to which they are included in the fair value of
      the asset; and discontinued operations are defined more broadly than under
      existing rules. The adoption of this new standard had no impact on the
      Company's financial statements since the Company did not have such
      operations.

      b)    STANDARDS APPLICABLE FOR FISCAL YEAR 2004

      GENERALLY ACCEPTED ACCOUNTING PRINCIPLES

      In July 2003, the CICA issued new Handbook Section 1100 "Generally
      Accepted Accounting Principles" ("GAAP"), which is effective for fiscal
      years beginning on or after October 1, 2003. This new section defines
      GAAP, establishes the relative authority of various types of CICA
      Accounting Standards Board pronouncements, says what to do when the
      Handbook does not cover a particular situation and clarifies the role of
      "industry practice" in setting GAAP. The Company will adopt this new
      standard on January 1, 2004. Adopting this standard is not expected to
      have a significant impact on the Company's financial statements.

      GENERAL STANDARDS OF FINANCIAL STATEMENT PRESENTATION

      In July 2003, the CICA issued new Handbook Section 1400 "General Standards
      of Financial Statement Presentation" which is effective for fiscal years
      beginning on or after October 1, 2003. This new section confirms that the
      financial statements of an entity must present fairly in accordance with
      Canadian generally accepted accounting principles its financial position,
      results of operations and cash flows. The Company will adopt this new
      standard on January 1, 2004. Adopting this standard is not expected to
      have a significant impact on the Company's financial statements.

      HEDGING RELATIONSHIPS

      The CICA has issued Accounting Guideline 13 "Hedging Relationships", which
      establishes certain conditions regarding when hedge accounting may be
      applied and which is effective for fiscal years beginning on or after
      January 1, 2004. AcG 13 addresses the identification, designation,
      documentation, and effectiveness of hedging transactions for the purposes
      of applying hedge accounting. It also establishes conditions for applying
      or discontinuing hedge accounting. Under this new guideline, the Company
      will also be required to document its hedging transactions and explicitly
      demonstrate that the hedges are sufficiently effective in order to
      continue hedge accounting for positions hedged with derivatives. Any
      derivative instrument that does not qualify for hedge accounting will be
      reported on a mark-to-market basis in earnings. The adoption of this
      guideline as at January 1, 2004 will not have any significant impact on
      the Company's financial statements since there are no significant hedging
      transactions as of this date.


4     BUSINESS ACQUISITIONS

      ACQUISITIONS IN 2003

      a)   Interchemical S.A. and Chimiray S.A.

           On August 5, 2003, Unipex, a French subsidiary of Atrium, acquired
           100% of the issued and outstanding common shares of Interchemical
           S.A. and Chimiray S.A. for a total consideration of $18,689,300 of
           which an amount of $14,184,390 was paid cash, net of cash and cash
           equivalents acquired of $3,583,081, and $921,829 as a balance of
           purchase price, non-interest bearing, payable on January 15, 2004.
           These companies are specializing in the distribution of fine
           chemicals and active ingredients. The results of operations have been
           included in the statement of operations since August 5, 2003, being
           the date of acquisition. Concerning the acquisition of these
           companies, an independent valuation report was issued on October 1,
           2003 confirming that no specific identifiable intangible assets has
           any material value which could be separated from goodwill.

      b)   Siricie S.A.

           On November 18, 2003, Atrium acquired 100% of the issued and
           outstanding common shares of Siricie S.A. for a total consideration
           of $2,039,721 of which an amount of $1,810,849 was paid cash, net of
           cash and cash equivalents acquired of $73,867, and $155,005 as a
           balance of purchase price, non-interest bearing, payable at the
           latest in October 2004. This company is specializing in the
           development of active ingredients drawn from marine life for the
           cosmetics industry. The results of operations have been included in
           the statement of operations since November 18, 2003, being the date
           of acquisition. The purchase price allocation shown is preliminary
           and is based on the Company's estimates of fair value. The final
           allocation is expected to be completed within the next six months and
           may result in a portion of the purchase price being allocated from
           goodwill to identifiable intangible assets.

           Goodwill is not deductible for income tax purposes.

      c)   Product line acquired in 2002 by Atrium Biotech USA Inc.

           The contingent payments in 2003 resulting from the acquisition of a
           product line in 2002 by Atrium Biotech USA Inc., a subsidiary of
           Atrium, amounted to $40,000 (US$30,336). That amount has been
           recorded as goodwill. Atrium Biotech USA Inc.
           does not expect to incur any additional payments.

      d)   Unipex

           On January 13, May 27, and July 16, 2003, Atrium acquired 23,760
           common shares of the outstanding capital stock of Unipex for a cash
           consideration of $2,843,766. Those acquisitions have been accounted
           for as step acquisitions. Atrium also made an additional investment
           by acquiring 70,400 treasury common shares of Unipex, increasing its
           interest to 80.65% (70.28% in 2002). The excess of the purchase price
           over the net identifiable assets on the date of acquisition is
           $3,174,618 and is recorded as goodwill not deductible for income tax
           purposes.

      e)   Gain (loss) on dilution

           On May 27, 2003, pursuant to the issuance of 2,200 common shares by
           Unipex, a loss on dilution amounting to $66,544 was recognized.

           On September 14, 2003 as a result of the issuance of 2,000 shares by
           Atrium, a gain on dilution amounting to $2,137 was recognized.
           Subsequently, as a result of the redemption of those shares, goodwill
           amounting to $9,375 was recognized.

      ACQUISITIONS IN 2002

      f)   Zentaris

           On December 30, 2002, AEterna GmbH, a new subsidiary of AEterna,
           acquired 100% of the issued and outstanding shares of Zentaris.
           Zentaris is an integrated biopharmaceutical and biotechnological
           company which develops and produces innovative products and
           technologies for patient-friendly therapies in oncology and
           endocrinology.

           The net assets acquired and the purchase price were subject to
           adjustments subsequent to the review of the audited financial
           statements of Zentaris as at December 31, 2002. Following the
           adjustments relating to the review of the audited financial
           statements of Zentaris in December 31, 2002, the total consideration
           paid for the acquisition of Zentaris is $85,494,850
           (euro 51,917,491).

           The purchase price allocation, following the acquisition of Zentaris'
           shares in December 2002, was finalized upon receipt of an independent
           valuation report during the second quarter of 2003, resulting in a
           decrease of $19,583,843 in intangible assets, $8,041,577 in future
           income tax liabilities and in an allocation of $11,542,266 as
           goodwill. On the acquisition date, two products developed by Zentaris
           have generated profits resulting from their sales. The developed
           technology and in-process research and development (R&D) have been
           valued using a discounted cash flow approach, resulting in an
           allocated fair value of $66,942,949. The goodwill related to this
           transaction amounted to $11,542,266 and it will not be amortized but
           tested annually for impairment in relation to the fair value of this
           reporting unit to which goodwill applies. The results of operations
           have been consolidated in the statement of operations from December
           30, 2002, being the date of acquisition.

           The balance of purchase price, bearing interest at the EURIBOR rate
           for a three-month term deposit plus 1%, was due and payable on the
           earlier of September 30, 2003 or the merger date of AEterna GmbH and
           Zentaris. This amount was offset in 2003 against the receivable from
           a former affiliated company of Zentaris resulting in a cash
           disbursement of $2,358,000.

      h)   Other acquisitions

           On April 15, 2002, Atrium Biotech USA Inc. acquired a product line
           for a total cash consideration of $435,394. The acquisition was
           subject to contingent payments specified in the agreement for a
           maximum amount of $300,000 of which $100,000 were paid and recorded
           as goodwill in 2002. The balance of $200,000 may be payable at the
           latest in October 2003 if the related conditions have been met; it
           will be then recorded as goodwill. The results of operations of this
           acquisition have been included in the statement of operations since
           April 15, 2002, being the date of acquisition. Based upon the
           allocation of the purchase price, the transaction resulted in
           $212,134 of goodwill and $223,260 of inventory. The goodwill acquired
           is deductible for income tax purposes.

           On September 8, 2002, Atrium acquired 300 common shares of the

           latter to 70.28% (70.2% in 2001) for a cash consideration of $31,171.
           The excess of the purchase price over the net carrying value on the
           date of acquisition is $26,221 and is recorded as goodwill not
           deductible for income tax purposes.

      i)   Gain on dilution

           On September 13, 2002, as a result of the issuance of 166,667 shares

14    EMPLOYEE FUTURE BENEFITS

      Some group companies in France and in Germany provide unfunded defined
      benefit pension plans for some classes of employees. Provisions for
      pension obligations are established for benefits payable in the form of
      retirement, disability and surviving dependant pensions. The benefits
      offered vary according to the legal, fiscal and economic conditions of
      each country.

      The following table provides a reconciliation of the changes in the plans'
      accrued benefits obligations:

      Pensions of former employees are not increased.

      With the exception of those offered by Zentaris acquired on December 31,
      2002, the employee future benefits maintained by one of the Company's
      subsidiaries are not significant and therefore, the disclosures otherwise
      required for the years ended December 31, 2001 and 2002 have not been
      provided.


15    SHARE CAPITAL

      d)   Company's stock option plan

           In December 1995, the Company's Board of Directors adopted a stock
           option plan for its directors, senior executives, employees and other
           collaborators providing services to the Company. The number of shares
           that are issuable under the plan shall not exceed 4,069,352. Options
           granted under the plan expire after a maximum period of ten years
           following the date of grant. Options granted under the plan generally
           vest over a three-year period.

           Had compensation costs been determined using the fair value method at
           the date of grant for awards granted during 2002 under this stock
           option plan, the Company's pro-forma net loss, basic and diluted loss
           per share for the year ended December 31, 2003 would have been
           $29,368 and $0.68 ($26,039 and $0.67 in 2002).

      e)   Atrium's stock option plan

           On November 1, 2000, the Board of Directors of Atrium adopted a stock
           option plan for its directors and employees providing services to
           Atrium. The exercise price of these options is equivalent to their
           fair value established annually from a specific formula and approved
           by the Board of Directors. The number of shares that are issuable
           under the plan shall not exceed 650,000. Options granted under the
           plan generally vest over a five-year period, with 20% vesting on an
           annual basis starting on the first anniversary of the date of grant,
           and they expire after a maximum period of ten years following the
           date of grant.

           The Company's ownership percentage of the subsidiary will change as a
           result of future exercises of stock options and outstanding
           subsidiary stock options may dilute the Company's share of profits in
           the calculation of loss per share.

</Table>

      As at December 31, 2003, the Company has non-refundable research and
      development tax credits of $12,489,000 which can be carried forward to
      reduce Canadian federal income taxes payable and expire at the latest in
      2013. No tax benefit has been accounted for in connection with those
      credits.

      The carryforwards and the tax credits claimed could be subjected to a
      review and a possible adjustment by the Canadian federal and Quebec
      provincial tax authorities.

      The majority of the loss carryforwards will expire no later than December
      31, 2010.

20    LOSS PER SHARE

      The following table summarizes the reconciliation of the basic weighted
      average number of shares outstanding and the diluted weighted average
      number of shares outstanding used in the diluted net loss per share
      calculation:

</Table>

      For the years ended December 31, 2003, 2002 and 2001, the diluted net loss
      per share was the same as the basic net loss per share since the dilutive
      effect of stock options and convertible term loans was not included in the
      calculation; otherwise, the effect would have been anti-dilutive.
      Accordingly, the diluted net loss per share for those years was calculated
      using the basic weighted average number of shares outstanding.

      FOREIGN CURRENCY RISK

      Since the Company operates on an international scale, it is exposed to
      currency risks as a result of potential exchange rate fluctuations. As at
      December 31, 2003, there are no significant outstanding forward exchange
      contracts.

      FAIR VALUE

      Cash and cash equivalents, short-term investments, accounts receivable,
      accounts payable and accrued liabilities and balances of purchase price
      are financial instruments whose fair value approximates their carrying
      value due to their short-term maturity. The fair value of short-term
      investments is $42,046,465 ($69,925,301 in 2002). The fair value of
      long-term debt and convertible term loans has been established by
      discounting the future cash flows at an interest rate corresponding to
      that which the Company would currently be able to obtain for loans with
      similar maturity dates and terms. The fair value of long-term debt and
      convertible term loans is $45,727,332 ($13,427,346 in 2002).

      CREDIT RISK

      Financial instruments which potentially subject the Company to
      concentrations of credit risk consist primarily of cash and cash
      equivalents, short-term investments and accounts receivable. Cash and cash
      equivalents are maintained with high-credit quality financial
      institutions. Short-term investments consist primarily of bonds issued by
      high-credit quality corporations and institutions. Consequently,
      management considers the risk of non-performance related to cash and cash
      equivalents and short-term investments to be minimal.

      Generally, the Company does not require collateral or other security from
      customers for trade accounts receivable; however, credit is extended
      following an evaluation of creditworthiness. In addition, the Company
      performs on-going credit reviews of all its customers and establishes an
      allowance for doubtful accounts when accounts are determined to be
      uncollectible.

-------------------------------------------------------------------------------

(tabular amounts in thousands of Canadian dollars,
except share/option and per share/option data and as otherwise noted)

      a)   STOCK-BASED COMPENSATION

           Through December 31, 2002, the Company and its subsidiaries accounted
           for their stock-based compensation plan under the intrinsic value
           method in accordance with APB 25. There is no expense recognized for
           stock options as they were granted at the stock price on the grant
           date and, therefore they have no intrinsic value. Effective January
           1, 2003, the Company has adopted Statement of Financial Accounting
           Standard ("SFAS") No. 123 using the prospective transition method.
           SFAS 123 requires all stock-based compensation awards, including
           stock options, to be accounted for at fair value. Under this
           prospective transition method, all new awards granted to employees on
           or after January 1, 2003 are accounted for at fair value. Awards
           outstanding as of December 31, 2002, if not subsequently modified,
           continue to be accounted for under APB 25. Fair value is based on a
           Black-Scholes valuation model with compensation costs recognized in
           earnings over the required service period. The Company provides
           additional pro-forma disclosures as required under SFAS No.123 for
           stock options granted before the adoption of this standard.

           As required under Canadian GAAP, all stock-based compensation awards
           granted since January 1, 2003 have been expensed in the financial
           statements using the fair value method. Pro-forma disclosures are
           required for stock options granted to employees from January 1, 2002
           to December 31, 2002.

      b)    REDEEMABLE COMMON SHARES OF THE SUBSIDIARY

           As required under Canadian GAAP, redeemable common shares of the
           subsidiary, issued in 2000, that were redeemable at the option of the
           holders were classified as liabilities in accordance with the
           substance of the contractual arrangement and the definition of a
           financial liability, and the accretion of the redeemable common
           shares is recorded as interest expense. Under U.S. GAAP, those shares
           are considered as "mandatorily redeemable"; they were then classified
           outside of shareholders' equity and long-term liabilities, in the
           mezzanine section of the balance sheet. Interest expense was charged
           to deficit.

      c)    ORGANIZATION COSTS

           Under U.S. GAAP, all organization costs are expensed as incurred.
           Under Canadian GAAP, organization costs are accounted for as
           intangible assets and are amortized on a straight-line basis over a
           five-year period.

      d)   RESEARCH AND DEVELOPMENT COSTS

           Under U.S. GAAP, all development costs are expensed as incurred.
           Under Canadian GAAP, development costs which meet generally accepted
           criteria for deferral are capitalized and amortized. As at December
           31, 2003, the Company had not deferred any development costs.

except share/option and per share/option data and as otherwise noted)

           Furthermore, under U.S. GAAP, in-process research and development
           acquired in a business combination is written off at the time of
           acquisition and no future income taxes are recognized on this asset
           in the purchase price allocation process. Under Canadian GAAP,
           in-process research and development acquired in a business
           combination is capitalized and amortized over its estimated useful
           life. Future income taxes are recognized on the acquisition date on
           that asset in the purchase price allocation process.

      e)   SHORT-TERM INVESTMENTS

           Short-term investments, which are classified as available-for-sale
           securities, include the Company's investment in bonds for which the
           Company does not have the positive intent or ability to hold to
           maturity. Under U.S. GAAP, available-for-sale securities are carried
           at fair value with unrealized gains and losses net of the related tax
           effects as part of other comprehensive loss.

           Under Canadian GAAP, short-term investments are valued at the lower
           of amortized cost and market value.

      f)   CONVERTIBLE TERM LOANS

           Under Canadian GAAP, proceeds from the issuance of convertible term
           loans are allocated among long-term convertible term loans and
           shareholder's equity, resulting in a debt discount that is amortized
           to expense over the term of the loans. The financing costs related to
           those loans have been allocated on a pro-rata basis between deferred
           charges and other capital. Under U.S. GAAP, those costs are all
           included in deferred charges and amortized over the term of the
           loans, and convertible term loans are totally considered as long-term
           debt.

      ACCOUNTING FOR STOCK-BASED COMPENSATION

      Under U.S. GAAP, the Company shall measure compensation cost related to
      awards of stock options using the intrinsic value method of accounting. In
      this instance, however, under SFAS 123, Accounting for Stock-Based
      Compensation, the Company is required to make pro-forma disclosures of net
      earnings (loss), basic net earnings (loss) per share and diluted net
      earnings (loss) per share as if the fair value based method of accounting
      had been applied.

      The fair value of options granted was estimated using the Black-Scholes
      options pricing model with the following weighted average assumptions: a
      risk-free interest rate of 3.72% for 2002 and 5.1% for 2001, an expected
      volatility of 57% for 2002 and 60% for 2001, dividends of nil and an
      expected life of 2.7 years for 2002 and 4.7 years for 2001. The weighted
      average grant-date fair value of options granted during the years ended
      December 31, 2002 and 2001 was $2.29 and $4.16, respectively.

-------------------------------------------------------------------------------

(tabular amounts in thousands of Canadian dollars,
except share/option and per share/option data and as otherwise noted)

      The Black-Scholes option valuation model was developed for use in
      estimating the fair value of traded options which have no vesting
      restrictions and are fully transferable. In addition, option valuation
      models require the input of highly subjective assumptions including the
      expected stock price volatility. Because the Company's employee stock
      options have characteristics significantly different from those of traded
      options, and because changes in the subjective input assumptions can
      materially affect the fair value estimate, in management's opinion, the
      existing models do not necessarily provide a reliable single measure of
      the fair value of its employee stock options.

      If the fair value based method had been used to account for stock-based
      compensation costs related to stock options issued to employees before
      January 1, 2003, the net loss and related net loss per share figures under
      U.S. GAAP would be as follows:

      UNAUDITED PRO-FORMA INFORMATION ON BUSINESS ACQUISITIONS

      Under U.S. GAAP, pro-forma information must be provided as though the
      business acquisition had occurred at the beginning of the reported
      periods.

      The following unaudited pro-forma information reflects the results of
      operations as if the 2002 acquisitions had been completed on January 1,
      2002.

      Such information is not necessarily indicative of the actual results which
      would have been achieved, nor is it necessarily indicative of future
      consolidated results of the Company:

24    COMPARATIVE FIGURES

      Certain comparative figures have been reclassified to conform with the
      current year presentation.


25    SUBSEQUENT EVENT

      On March 3, 2004, Atrium, through its new incorporated subsidiary, Atrium
      Pureco, Inc., completed the acquisition of the operating assets of Pure
      Encapsulations, Inc. for a total consideration of approximately
      US$37,100,000 ($50,000,000) of which an amount of US$35,000,000 will be
      paid cash and US$2,100,000 as a balance of purchase price. This company,
      based in the United States, is focused mainly on the development,
      manufacturing and marketing of nutritional supplements geared towards
      physicians and other healthcare professionals. The financing of the
      transaction resulted from the issuance of a senior debt of $27,000,000 and
      a subordinate debt in the amount of $13,407,000.

      This acquisition will be accounted for using the purchase method and the
      results of operations will be included in the consolidated financial
      statements of the Company from the date of acquisition, being March 3,
      2004.
